• The localloop can be viewed as the last mile of the telecommunication network which exists between the central offices (C0) and the individLial homes, small businesses and mar kets, and big businesses near the CO as show in fig.

• In the developed countries the copper (co-axial cableso or optical cables for the homes and businesses are already laid down. But in many developing nations it is not so. There the cables are too expensive or can take long time to get installed.

• A great advantage of the wireless equipments how ever is that it can be deployed within a few hours. One more a advantage of WLL technology is that we have to pay only once for the wireless equipment. After that there are no additional costs involved.

• The WLL technology is capable of competing with the copper wire based Digital subscriber loop (DSL) technology which is growing very fast. The WLL can greatly improve the telecommunication facilities and services in an inexpensive way.
